yaay i finished the sketch!!!

Whenever Megatron wakes up, he remembers he’s all alone.

(We love rarepairs in this house! Also this is G1, since you said Skyfire and not Jetfire)

The size difference was a consistent issue. Cosmos wasn't necessarily small by Autobot standards, but Skyfire's size could dwarf most of their army.

That said, they had their workarounds.

"This feels kind of...silly."

Cosmos paused in his movements. "Do you want to stop?"

Skyfire shook his head. "No. I'm just not sure if this will work the way you're wanting it to. I mean, do people really get off this way?"

"I read about it in a romance novel."

"Well that explains a lot," Skyfire chuckled.

Cosmos had to admit his point. Skyfire was currently on his back, legs bent so that his feet were resting on the berth, but spread so that Cosmos could settle between them. Because Cosmos was on the wider side, he was sat perpendicular to Skyfire so that he could hold onto his leg and use it as leverage once they started. From and outside perspective, the positioning probably did look a bit silly.

(HELL YEAH)

"After millions of years under my command, I would have thought I'd taught you better preservation skills by now."

Chromia felt a playful smirk coming on as she listened to the hum of her Commander's words in her audial. Elita-1 was warm where she leaned against her back, face close to Chromia's audial as she typed the day's reports into their computer.

"Come on now, I wasn't that reckless," she countered. "I kept the others in check at least."

"You could have been hurt."

(👏👏👏 Thank you for waiting patiently, my brain's been horrible lately~)

"Prime, we need to recharge at some point tonight, and at this rate I might drop off with your fingers still inside me."

Optimus grunted, annoyed. Megatron was bluffing; he was clearly very close to overload, his valve already giving telltale contractions around the Prime's digits. But, as usual, he was going fight Optimus on this and refuse to be the first one to finish.

Fine then. If he wanted to be difficult, Optimus could do the same.

He pulled out, slick running all the way down his wrist, and he didn't miss the little moan Megatron gave at the lost sensation. Before he had time to say anything else, Optimus flipped him to lie on his back.

"Ugh. Finally."

Megatron spread his legs wide, then reached down to spread the lips of his valve as well. A smirk grew on his lips.

"Don't act like you haven't been craving it."

He was craving it. That familiar warm heat, the way Megatron's valve encased him in its soft, delicious grip-

But he knew Megatron craved it too, and he was in no mood to reward him.

Instead...

Fingers still slick with lubricant, Optimus reached down, past the offered valve, to rub at the port below. Megatron startled a bit at the contact, clenching involuntarily.

"What are you-?"

Before the question could be finished, Optimus had already slipped a digit inside. This earned him a gasp, and a demonstrative squeeze around his fingers.

Optimus grinned to himself - he would enjoy this. He looked up to do a quick check, and saw Megatron watching him apprehensively. Optimus sent him a quick comm to check if he needed to use their safeword, just in case.

In response, Megatron swallowed before shaking his head and sending back a message telling Optimus to go ahead. This wasn't what he had prepared for; he'd spent most of the day waiting for his valve to get properly ruined. He also hadn't used his port much, and thus wasn't sure what he should expect. But he wasn't the type to back down from a challenge.

He soon thanked himself for forging on. After some quick prep work, with Optimus using the combined lubricants from his own spike and Megatron's valve, he finally entered. It was a tight fit, and he had to pause to let Megatron adjust, but it wasn't long before he was delivering steady, firm thrusts that lit up his partner's sensors.

Megatron shut his optics and tightened his jaw as he focused on the sensation. The entrance, the insistent stretching had rendered him speechless. Unlike the the node-lined texture of his valve, the aft port (mainly medical in purpose) was metal and thin tubing - more sensitive, but in a way that didn't translate to his processor as pleasure so much as raw sensation. And now that he was thrusting, the way the ridges on Optimus's spike teased that lining made him want to squirm. He was completely out of his element, overwhelmed, warring between wanting to get away from it and wanting as much as he could get.

"Enjoying yourself?" Optimus's voice was teasing, but rough with lust.

Megatron opened his mouth to retort but only a gasp came out as the Prime began to quicken his thrusts. Optimus shifted Megatron's legs to go over his shoulders, practically bending him in half so that he could drill even deeper into him.

The charge kept building, his heat levels were rising, and Megatron found himself completely unable to issue his usual round of dirty talk. He could only cling to Optimus as he felt the sensation coil inside him, tighter and tighter as it waited to snap. His poor, neglected valve wept lubricant that dripped down to his aft, making a wet surface for Optimus to slam his hips against.

Megatron felt wrecked. He felt pathetic and used.

Fuck if he didn't love it.

"Please," he murmured. His voice was faint enough that Optimus had to slow his pace and ask him to repeat himself. It was humiliating, but Megatron hardly cared anymore and he was practically whimpering as he repeated, "Please. I want it."

Apparently Optimus liked seeing him so low, because before he could say any more, the Prime had let go of his legs and was hauling him into his lap to hold him tight as he pistoned up into him. It was fast and desperate, until he finally stuttered in his motion and Megatron could feel him finishing inside.

That hot flood of transfluid washing over his sore, abused sensors finally did him in. Every biolight on Megatron's frame lit up as overload slammed through him, and he arched back in Optimus's grip, completely overcome.

It lasted a good while, and his valve made more of a mess than usual. Even once the main overload had ceased, Megatron could still feel himself twitching rhythmically for several minutes after while Optimus cradled him in his arms.

"I might have overdone it," Optimus murmured, apologetic.

Megatron tried to shake his head but couldn't.

"Are you alright?"
